Hi, I have MVC project my  code need to check that this code exist in data base if exist prevent submission else submit normally  I try  make it with Json
this is my Razor View

@using (Html.BeginForm(actionName: "Create",
                  controllerName: "Employee",
                  method: FormMethod.Post,
                  htmlAttributes: new { enctype = "multipart/form-data", @id = "form-horizontal", @class = "form-horizontal form-wizard-wrapper text-right form-parsley" }


    <div class="col-md-6">
        <div class="form-group row">
            <label for="txtAddress2Billing" class="col-lg-3 col-form-label">Code</label>
            <div class="col-lg-8 form-group" id="classcode">
                @Html.EditorFor(model => model.code, new { htmlAttributes = new { @type = "Text", @class = " form-control", @id = "Code", @oninput = "CodeCheck()" } })
                @Html.ValidationMessageFor(model => model.code, "", new { @class = "text-danger" })
            <p id="Status" class="col-lg-1 mt-2" />
        </div><!--end form-group-->
    </div><!--end col-->

    <div class="form-group row">
        <div class="col-lg-2"></div>
        <div class="col-lg-3">
            <input type="submit" value="Create" class="btn btn-outline-warning" style="width:150px;" />
        <div class="col-lg-3">
            <a href="~/EmpDatas/Index" class="btn btn-outline-warning" style="width:150px"> Cancel</a>


<script src="~/assets/js/jquery.min.js"></script>
<script src="~/assets/js/bootstrap.bundle.min.js"></script>
<script src="~/assets/js/app.js"></script>


      function CodeCheck() {
          $("#Status").html('<i class="fas fa-spinner fa-pulse"></i>');
        $.post("@Url.Action("CheckCodeAvailability", "Employee")",
                Code: $("#Code").val()
        function (data) {
            if (data == 0) {

                $("#Status").html('<i class="far fa-times-circle text-danger"></i>');
                $("#Code").css("border-color", "Red");
            else {
                $("#Status").html('<i class="far fa-check-circle text-success"></i>');
                $("#Code").css("border-color", "Green");

and This is my Json code

public JsonResult CheckCodeAvailability(string Code)

            var exist = db.EmpDatas.Where(m => m.code.ToString() == Code).Count();

            if (exist < 1)
                return Json(1);
                return Json(0);
